more soil questions, noob strikes again! Options

So I've been digging at this river for a few days and I've noticed some interesting soil deposits. I'm wondering if they are even worth my time. In one area there is an eroding man made rock slide area that backs to a willow covered plain. I went digging into it today and found a decomposing vegitation/mud/black sand layer underneath there I found a rusty sandy lome layer. It seems to be untouched by others judging by the red stained rocks I went through.
There is another section I played in across the river where there is a dark black sand area that has black stained rocks with silver streaks running through the stones. Above the dark sand area is a normal river sand layer.
Do either of these sound like it's better to dig through? Or if I need to provide more information?

I hear ya there, I didn't even go to work today, just to dang cold to go outside period. In time we will be able to meet up at the creek, we really do need the moisture though so I'll give it that.

The cabin fever is REALLY starting to set in, I bet Betsy is going nuts as well. I've got some concentrait from this last summer, just might have to work it in the finish pan, to cold to sit out in the garage and run the blue bowl, and the law is I can't set up the equipment in the house, LOL.

Well I better get back to my school work, have a great week and stay WARM!
